I've seen some crazy videos online of the devastation that TC sounds subs do to cars (warping roofs, breaking windows etc...) but these were the largest subs they make with a TON of power. Just based off what I have read is that they are a great sub for volume but not for creating music. I do not have the most reliable feedback because I have not heard them in person or have any feedback on any of the other subs they make. I'm guessing it is the Epic series because they do not list a TC3000. Based off the specs it should play nice and deep but is not very efficient.
What sub are you replacing (any likes or dislikes)?
What size enclosure and ported, sealed, bandpass?
What amp are you using?
What style of music do you listen to?
What highs and tower speakers are you running with how much power?
^^^^These are all things the local audio store should have asked. Let me know and I'll give my suggestion.
